Node.js module cannot be required

Question

I have written a Node.js server on the Raspberry pi, and have successfully previously used several modules in it.

However, in the most recent version, which requires the package serialport, I have received the following error message:

 /home/pi/hub/node_modules/serialport/node_modules/bindings/bindings.js:85
  throw err
        ^
Error: Could not load the bindings file. Tried:

I have tried searching for this error, including on stackoverflow, but the few solutions that I found did not fix the problem.

UPDATE:

For reasons I cannot discern, I'm now getting a different error. I don't remember changing anything.

/home/pi/hub/node_modules/serialport/node_modules/bindings/bindings.js:77
        throw e
              ^
Error: Unable to load shared library     /home/pi/hub/node_modules/serialport/build/Release/serialport.node

I've doublechecked, and I'm pretty sure that serialport is installed in the right directory

Turns out that this will work if you install an earlier version of serialport:

npm install serialport@0.7.3

Guess the later versions weren't compatible with my version of nodejs
